SPECIFICATION f r g p of et er Paten No. 775,848, dated November 22, 1904.

Application filed April 1, 1904 To all] whom it may concern.-

Be it known that I, SAMUEL F. M CCLANE, a citizen of the United States, residing at Owatonna, in the county of Steele and State of Minnesota, have invented new and useful improvements in Ohurns, of which the following is a specification.

This invention relates particularly to churns or butter-extractors of that type having a rotary dasher set upon a vertical shaft, and it is characterized iiarticularly by improvement with respect to the dasher and a removable rim or ring carried at the outer ends of the blades of the dasher, the general operation being such that the cream is forced by the dasher to circulate up one side of the rim and down the other, thus insuring a complete agitation and separation.

1n the accompanying drawings, Figure l is a vertical sectional elevation of the churn. Fig. 2 is a side elevation of the dasher and its shaft. Fig. 3 is a bottom plan view of the removable rim which is carried by the dasherblades.

Referring specifically to the drawings, 6inf dicates a can which sits on a base'7, from which projects a vertical standard 8 beside the can, and this standard has at the top an arm 9, which hangs over the can. This arm carries the gearing and also supports the dasher-shaft 10, the lower end of which finds a bearing in the bottom of the can and the other end of which has a pivot bearing upon a pin 11, which fits through a hole in the end of the overhanging arm and is held in place by a set-screw 12. By removing the pin 11 the shaft 10 and dasher can be swungout and lifted from the can.

The operating crank-shaft is indicated at J 13, carried 111a bearing in the intermediate portion of the standard 8 and having a spurwheel 14: in mesh with a spur-pinion 15 on a horizontal shaft 16, which is provided at its Serial No; 201,141. (No modehl bevel-gear 18 on the shaft 10. The shaft '16 also carries at its outer end a fly-wheel 19.

The dasher comprises a sleeve 20, fixed to the shaft 10 by set-screws 21, whereby it may be set at any height desired, and projecting g from this sleeve are blades 22, preferably four in number. These blades have a narrow portion QZ near the sleeve, enlarging to a wide portion 29." at about the middle and decreasing in width at the end, as at 22, terminating I finally in upwardly-projecting lugs 22 at the outerends. The blades are gradually inclined transversely of their longitudinal axis to cf- 1 inner end with a be\"el-gear 1T, meshing with l l At 23 a ring or rim is indicated 23, which I The ad vantage of having the rim removable i from the dasher is that it is easier cleaned t after churning and is not so liable to be broken; but if broken it can be replaced without prol vidingan entirely new dasher. Furthermore,

an advantage of operation is obtained. VVhen the butter begins to gather, it desirable r that the rim be removed, at which time it is simply necessary to slip the rim oil of the dasher and shaft, after which by turning the i crank a few times the butter is gathered at the top. This is advantageous because if the rim is fastened to the dasher the butter falls over the outside thereof and is apt to be broken or dispersed and also makes the machine turn very hard. By permitting the rim to be removed when the butter begins to j gather it can be'gathored properly and quickly. I The shape of the blades shown has also been found by experiment to be most advantageous for the operation desired. The sides of the l can have vertical balllc-strips 6 thereon to agitate the cream and throw the same toward the dasher.

hat I claim as new, and desire to secure by Letters Patent, is-

1. In a churn, a rotary dasher comprising a plurality of blades, and a removable ring carried on the outer ends of the blades.

2. In a churn, a rotary dasher comprising a plurality of blades having upwardly-pro- IO jeoting lugs at the outer ends, and a removable ring having at the lower edge sockets in which the lugs fit.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
